To aZZ whom it may concern.-

Be it known that I, WILLIAM HINOHLIFFE, of Nashville, county of Davidson, and State of Tennessee, have invented an Improvement in Spindle-Supports for Spinning Machines, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawing representing like parts.

This invention has for its object the production of an improved spindle-support having provision to permit the lower end of the spindle to move as the spindle seeks to find its true center under an unbalanced load.

In thisinvention the bolster-case is provided with a bolster, which is held rigidly therein, the bolster being open at its lower end, and below the bolster is a loosely-held step,which is restrained from rotation with the spindle, the said step, as herein shown, being mounted on a vertical pin or stud. 5

My invention 'is shown as embodied in a sleeve-whirl spindle.

With a-spindle such as herein shown the employment of elastic packing, so frequently used between the bolster and bolster-ease, is

not necessary. One part of the bolster for a portion of its length fits the bolster case snugly, while another part of the bolster, which fits the spindle more closely, is of such diameter externally that it rests within, but does not touch, the inner walls of the bolstercase, the absence of contact between the bolster and bolster-case lessening the transmission of jar.

The drawing shows a sleeve-whirl, a bolster, a step, a bolster-rail, and a nut in section, the spindle and pin for supporting the step being in elevation.

The bolster-rail A receives within it the bolster-case B, extended below the rail for, as herein shown, a considerable distance, and being held in place on the rail by a nut, B. The bolster a, made as a tube, is herein shown reduced in'diameter from the shoulder 2 to its upper end, the lower end of the bolster, of larger diameter, fitting the bolster-case rigidly, the portion of the bolster above the shoulder 2 being enough smaller in diameter externally to normally stand in the bolstercase without touching the inner wall thereof.

The downwardly-extended lower end of the bolster-ease has, as herein shown, screwed into it a nut, 11, which serves to hold a stud,

1), herein represented as tapering, the said stud supporting the spindle-step O, the latter being of considerably smaller diameter externally than the interior bore of the bolstercase, so that the step loosely fitted on the stud b has a freedom of motion or vibration laterallyin substantially every direction within the bolster-case below the bolster, the step so supported receiving within it the pintle 3 of the spindle D, the step thus held being adapted to move as the lower end of the spindle, in seeking its true center of motion under an unbalanced load, moves within the bolstercase.

The step 0 is prevented from rotation in the bolster-case by means of a screw pin or projection, e, extended through the bolstercase into the step. The sleeve-whirl is extended down about the upper end of the bolster-case.

In this as in other spindle-bearings there is a suitable space between the spindle and bolster for oil.

I do not claim a spindle supported directly upon a flexible or laterally-yielding pin, the spindle running in a bolster mounted loosely in a bolster-case. By holding the bolster rigidly the spindle is more accurately centered with relation to. the ring, and is also held more nearly perpendicular in rotation.

I claim- 1. The combination, with the bolster-case and bolster held rigidly therein, of a pin or step support and loose step free to move in any direction thereon with the lower end of the spindle as the latter centers itself to an unbalanced load, substantially as described.

2. The combination, with the bolster-case and bolster, held rigidly therein atoneend, of a loose step free to move in any direction with the lower end of the spindle as the lattercenters itself to an unbalanced load, and a pin or projection to prevent the rotation of In testimony whereof I have signed my name the step with the spindle, substantially as dcto this specification in the presence of two sub- 10 scribed. scribing witnesses.

3. The bolster-ease the bolster held rig- T idly therein, and the pin I), combined with CHLIFFD' the step mounted loosely on the said pin and Witnesses:

THOMAS HINOHLIFFE, J OHN T. Bnowx.

having a recess to receive the foot of the spindle, all substantially as described.
